MgO:Ce³⁺,Li⁺ was synthesized by the solid-state reaction (SSR) method and its luminescence properties were investigated. The X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM) images were used for the structure analysis. The luminescence properties were studied using thermoluminescence (TL), photoluminescence (PL), and radioluminescence (RL) techniques. The step annealing experiment was conducted to find the preheating temperature. The dose–response features as a function of β-ray exposure extended from 0.2 Gy to 2 kGy were investigated. The kinetic parameters such as the activation energy (E_a), frequency factors, and order of kinetics of MgO:Ce³⁺,Li⁺ were found using the computerized glow curve deconvolution (CGCD), variable heating rate (VHR) methods, and T_m-T_stop method in combination with the Initial Rise (IR) method. The experimental results of the TL, PL, and RL analyses can serve for a better understanding of the luminescent mechanism in Ce³⁺ and Li⁺ activated MgO for the potential use of designing phosphor as a dosimeter and optical ceramic material.
